Anrain Replacement Spa Pillow for Hot Spot & Caldera Spas — 3-Pack Cool Grey EVA, Ergonomic Neck Support

Anrain 76113 Replacement Spa Pillow is a three-piece set of cool-grey EVA neck pillows made to match Hot Spot and Caldera spa cushions for comfortable, heat-resistant head and neck support.

These replacement hot tub pillows are manufactured from high-density EVA foam with an internal mesh structure for fast drainage and long-term shape retention. Built to fit specific Hot Spot/Caldera models—including Relay, Rhythm, Tempo (2010–2014), Stride (2019–current) and several Vacanza, Palatino, Marino, Vanto, Aventine, Tarino and Celio series—this 3-pack restores the original seating comfort without changing your spa’s look or mounting system.

Which spa models will the 76113 pillow fit?

The Anrain 76113 is engineered to match original dimensions used by Hot Spot and Caldera for several model lines and years. Check compatibility with your spa’s manual or existing pillow shape before ordering to ensure a correct match.

• Relay / Rhythm / Tempo series: 2010–2014
• Stride series: 2019–current
• Vacanza, Palatino, Marino, Vanto, Aventine: 2010–current
• Tarino: 2013–current; Celio: 2019–current

How durable and weatherproof are these replacement pillows?

Constructed from dense EVA material, these pillows resist heat, water, and outdoor exposure while retaining their shape. Laboratory-style testing demonstrates stability under high temperatures, and the internal mesh promotes drainage so cushions dry quickly and avoid surface bubbling.

• High-density EVA resists deformation and UV-related breakdown
• Tested to withstand temperatures up to about 176°F (80°C)
• Internal mesh channels speed drainage and reduce water retention
• Cool grey finish resists visible fading and staining

Will the 76113 pillow improve comfort and support?

The ergonomic curvature supports the head, neck and upper shoulders to help reduce pressure points while you soak. With balanced resilience, the pillow cradles the neck gently to help sustain a relaxed position without flattening quickly.

• Contoured shape for natural neck alignment
• High resilience foam cushions without excessive sinkage
• Designed to reduce muscle fatigue during longer soaks
• Three-pack lets you replace multiple seats for consistent comfort

How simple is installation and upkeep?

Installation follows the original pillow mounting style so you can install replacement units in minutes without special tools. For routine care, rinse with fresh water after use and let air-dry; periodic replacement keeps hygiene and support optimal.

• Tool-free, original-style fit for quick swap-in installation
• Rinse and air-dry after use to remove residues
• Recommended replacement cycle: every 2–3 years depending on usage and exposure
• Backed by seller inspection and responsive after-sales support

Who is this for? Owners of Hot Spot or Caldera spas who need a faithful, durable replacement for worn or damaged neck pillows will appreciate the Anrain 76113 three-pack. It’s aimed at spa users who want an easy, original-fit swap with improved drainage and heat resistance—especially those replacing several pillows at once or restoring older model series to like-new comfort.
